BD3860K
BD3860K is High Definition Sound Processor manufactured by ROHM.
Description
The BD3860K is a sound processor IC for car audio applications. This IC provides treble clarity through the bass field incorporating function. This IC has clarity without increasing volume levels which makes it suitable for car stereo sound systems.
Dimension (Units : mm)
Features
1) Incorporates , 4-input selector (4-channel stereo), input gain, main volume, loudness, tone (2-band), fader volume. 2) Resistor ladder volume allows low distortion and low noise through the Bi-CMOS process. 3) 2-wire serial control. 4) Available in and QFP44 package, ideal for pact designs.
